NATIONAL WEATHER SUMMARY:
Showers and thunderstorms have been on the increase over the southeastern corner of the country today. The storms will be common across Florida, Alabama, Georgia and South Carolina this afternoon and evening. The storms are developing near an upper level storm that is located over the northern Gulf of Mexico. Some isolated
storms will also stretch from the lower Ohio Valley eastward into
the Mid-Atlantic region. Tropical Storm Danny continues to slowly
organize to the north of the Bahamas. Danny will head to the
northwest and should bring rain to the coast of North Carolina on
Friday morning. Tropical storm force winds may develop later on
Friday along the coast of North Carolina as the system approaches.
Excessive rainfall has been reported in the Midwest over the past 24 hours. A plume of tropical moisture flowing northward from
Mexico northeastward into the Midwest and Great Lakes has fueled
slow moving showers and thunderstorms from north central Oklahoma
through eastern Kansas, southern and eastern Iowa and northern
Illinois. Many locations within this area of received 2-4 inches of
rain in the past day, with some spots in southeastern Iowa picking
up more than 10 inches. Flash flooding has been occurring over
southeastern Iowa since last night with many rivers and streams
swollen due to the intense rainfall. The focus for more excessive
rainfall during the next day will be across the northern third of
Illinois, extreme southeastern Wisconsin and northwestern Indiana.
Several inches of additional rain is possible in this area with
some isolated heavier totals. Farther to the north, a cold front
dropping south from Canada will set off scattered thunderstorms
from North Dakota into northern Minnesota. Gusty winds and large
hail will accompany some of these storms into the evening hours.
The western part of the country will continue to experience warm and mainly dry weather. A few isolated storms will pop up over the mountains of New Mexico into western Texas this afternoon and early this evening. Temperatures will begin to warm along the West Coast.
